Homework Statement When the volume of a gas is reduced with fp% and the gas is heaten with ΔT K, the pressure of it grows with fp%.Find initial temperature Ti. Application: fv%= 20%; ΔT 12 K; fp% = 30% 2.A aluminium calorimeter with the mass m1 contains the mass m2 of water heated...

Try this problem:In a box closed by a piston is a quantity of ideal gas characterized whit the parameters p1,V1,T1.The gass is put to this processes: 1. izocore heating up to p1= 1,5p1 2.izobar uncompression up to V3= 2 V1 3. izocore cooling up to p4=p1 4. izobare comprimation up to...

but in izobaric process the Pressure is constant so we don't use it in equations :) this helps?

i don't know, doesn't mention but here are the answers W= 4,99 kJ Q = 17 Kj Δ U= 12,47Kj

R has the value 8.314 J·K−1·mol−1.

we got to exprime V2=V1 x K i think as it say that the second volume is rising by K times

yes bur for W what i do? how i fiend the pressure?

It say :The volume of a quantity of Hydrogen of mass m , found initial at the temperature t1, rises of K times in izobare dilatation.Fiend the W ,Q absorbed and the Delta u (Intern energy) m=2g t1=27 Celsius and k=2 For b i think is W=Delta U + Q i think

m= 2g t1=27 celsius=300 Kelvin k=3

and how do i find the p?

you said earlier that W= P x change in Volume Right? so what i do whit v1/t1=v2/t2? as i see nothing that can help in the above

what A means and =P x delta Volume is the equation to fiend W right? also how do i fiend the pressure? whit p1/t1=p2/t2?

W= p x V?? can you tell me what to do?

yes i found on wiki english its Work :) but we note it whit L so how i do the problem?

L- mecanic force idk how the say it in english its the mecanic stuff that in Mecanic phisics is L=f*d and the values are in joules
